Engineered water system for the London Clinic, UK
The Client
Established in 1932, The London Clinic is the largest independently owned charity hospital in the UK. The London Clinic has over 250 beds, seventeen operating theatres including dedicated endoscopy suites, a day surgery unit and three radiotherapy suites. The London Clinic was the first hospital in the UK to have access to the Olympus Lucera Spectrum state-of-the-art endoscopy imaging system, which allows diagnosis of cancers and premalignant conditions at an earlier stage.
The Requirement
The capability for early diagnosis led to an increase in demand and The London Clinic needed to expand its existing endoscopy facility to provide more treatment rooms. It took the opportunity to upgrade the existing endoscope reprocessing equipment and the associated water purification equipment. The London Clinic needed a continuous supply of high purity water meeting the latest regulatory guidelines. A new plant room was created in the roof space but, because it was divided into small sections, it was very difficult to fit in a standard model.
The Solution
ELGA Process Water's solution was to install an Osiris 600 duplex purification unit. This system duplication allows sanitisation and routine maintenance with no downtime within the Endoscopy Department. The standard Osiris unit was fully customised so that the entire system could be manufactured on three precision engineered skids to fit into the plant room. The pre-treatment plant was designed to feed not only the Osiris units but also the direct fired gas water heaters, which supply hot water to the AER units.
Results
In spite of access difficulties which required crane lifting of the skids to the 8th floor, the plant was installed on programme within the restricted space available. The treated water has consistently been fully compliant with the regulatory standards, with total viable bacteria count <10 cfu/100ml and endotoxins <0.25EU/ml. By introducing heat sanitisation, operating costs have been reduced by £4,000 per annum. Heat sanitisation is more environmentally friendly than chemical sanitisation and is carried out fully automatically outside working hours.
